To all whom it may concern:

Be it known that I, FEnENoz'I-IEIMLIoH, a citizen of the United States, residing in the city and county of San Franciscolandstate of California, have invented a new and use-. ful Improvement in Shoemakers Jacks, of

which the following is aspecification in such full and clear terms as will enable those skilled in the art to construct and use the same. g

This invention relates to .a jack used by shoemakers for the purpose of holding shoes and boots when they are repairing or working on them.

An object of the-invention is to produce a jack that will be about the right height for a man to work at when standing up, and which will have means for adjusting the height thereof.

Another object of the invention is to produce a jack that will be movable into almost any possible position, as when the sides of a shoe areto be worked on the last must be turned over on one side, or the other.

Another object of the invention is to produce a jack that will have such a look as will hold the last firmly in place in the jack at all times and in all positions in which the shoe may be worked in.

A still further object of the invention is to produce a jack that will be usable on a table or on a standard at the will of the operator.

An important object of the invention is to enable the workman to do handsewing without danger of having his waxed thread, or waxed end as it is commonly called caught and tangled or broken, since all portions of the outer portion of the jack are made as smooth as possible.

In the drawings, in which the same numeral of reference is applied to the same part throughout, Figure 1 is a sectional view of the jack, Fig. 2 is an elevation partly broken away taken at right angles to Fig. 1, Fig. 3 is an enlarged horizontal sectional view taken on the line a a of Fig. 1, Fig. 4 is an enlarged horizontal section taken on line b Z) of Fig. 1, Fig. 5 is a view in perspective of the last look in the top of the last standard, Fig. 6 is a sectional view taken on line 0 c of Fig. 3, Fig. 7 is a view of an iron last showing the last look, Fig. 8 is a side elevation of a bench jack and showing an iron last in place.

In Fig. 1 is shown a sectional view of the jack used when thesame is attached to the floor, and being bolted to the floor by means of the bolts 2 passing through the base 3. This post is hollow and has a foot lever 4 pivoted to it near the bottom thereof, a rack 5 being provided to hold the foot lever in any desired position. The lever is supported by means of the. bracket 6 having the up standing lug 7, saidbracket being secured to the base of the post 1. Near the upper end ofv the post there is pivoted the double pawl 8 carried by the, bar 8 which supports the standard 10 adjustably, the points of said pawl being large and heavy enough to with stand considerable hammering on the shoes. Slidable in the hollow post for the purpose of adjusting the height of the jack is a standard 10 which has a series of teeth 11 to correspond with the points of the pawls 8. This standard has a pair of heavy set screws 12 which pass into slots 16 and prevent the turntable carrier 13 from falling too low when the upper standard is pulled to the position shown in dotted lines. The top of the standard is provided with a pair of upwardly extending arms 14 on each side thereof and which form the means for supporting the turntable support 13, said support having downwardly extending ears 15 the same as the ears 14. This support also has two long slots 16 which allow it to be tilted over to one side till the bottom of the slots come into contact with the heavy set screws 12. Placed on the, turntable support ,is the turntable 17 which has four screws 18 which pass into a groove 19 in the turntable support and which hold the turntable securely to the support. Since there are substantially only three positions in which it is desirable to incline the post 25, the; turntable permitting any circular movement of the shoe, the base of the short post 13 is so made that it. will remain in only three positions. It will remain upright and at an incline on either side of the posts 10 and 17, the inclines of said posts holding it in one of the two positions when it has been moved out of the vertical position. This forms the means whereby the post may be quickly moved to either of the inclined positions without the necessity of turning a screw to hold it in that position.

The turntable can move no farther to one side or the other than is shown in dotted lines in Fig. 8, because the curved shoulders 14 come in contact with the straight inare formed the shallow depressions 21, the

purpose of which is to afford a place to set the shoe support 22 in, its base having a horizontally extending lug which is seated in the horizontal pocket in the turntable.

The turntable also has a pair of slots 23 at the side thereof and through which pass the ends of the strap 24, the purpose of which will beexplained later. 7

It will be notedthat the curved shoulders 14 more or less securely hold the turntable,

post in a vertical position, although permitting the same to be lifted up and shifted to the inclined position when so desired, in which event the shoulders contact with the straight inclines and tend to hold the turntable post always at substantially the same angle. In top of the turntable is a square hole which takes the lower end of the standard 25, said standard having its upper end cored out to take the various fittings used with thejack. All the iron lasts are equipped with the same kind of an extending tongue 26 in order that any of them may be interchanged at the will of the operator. The last look comprises a downwardly projeeting wedge having two outwardly projecting wedges on each side thereof, said wedges holding the last firmly in place to prevent any movement thereof during the operation of the shoe secured thereon. The jar of hammering is somewhat taken up by means of the leather washers W which are placed in the turntable and which also reduce the noise and prevent the turntable from turning around too easily.

l/Vhen shoes are made on a wood last it is necessary to hold the shoe firmly in a given position to do the work on it, this being accomplished by means of the toe support 22. This toe support is held in place in the side of the turntable and extends up to a point near the top of the standard where it spreads out into two plates 29 and 30. These plates 29 and 30 have their upper edges serrated in order that the toe post 31 may be moved to various positions and securely held in any of them, clamps 32 being provided to prevent the post 31 from rising out of the serrations and slipping. The support proper for the wooden lasts numbered 27 takes the place of the iron lasts, when the wood last is to be used, and has the upwardly extending plate 33 to which the pin 34 is pivoted, said pin having the depending plates 35 and 36 on each side of the plate 33, and they bear on spiral springs 37 and 38 which are held in place by means of the plates 39 and 40 shown in detail in the drawings. These plates are secured to the base of the wood last support by means of two screws and they have a stop at each end, one to prevent the spiral springs 37 and 38 from moving out of the space between the plate 33 and the plates 39 and 40, and the other to prevent the plates 35 and 36 from being pushed out of the channel they rest in.

hen a wood last is placed on the pin 34- it is caused to hold the toe of the shoe very much below the top of the toe post 31. The workman then catches the shoe by the toe and lifts it high enough to rest on the toe post, when the springs hold it firmly in place. Even when a. wood last is used it is necessary to hold the shoe and last very firmly in place onthe post, and when the iron lasts are used in repair work it is essential that some means he provided to make the shoe press down closely to the last to give the worker an opportunity to do his work well. This is accomplished by means of the strap 24; having a buckle -13 and which passes down into the interior of the main post through slots in the turntable.

Secured to the lower end of the loop of the strap Qt are a swivel joint S and a long loop of wire cable at, to the lower end of which is secured the rod l5 which is connected with the foot lever. The object of this long loop of cable is to permit a pin 46 to hold the swivel in one position thus causing the swivel to work better than if allowed to be twisted first to one side and then to the other.

In the form of the invention shown in Fig. 8 the only change is that the post 47 is made short enough to be secured upon a table or bench of the usual height, the strap being tightened over the shoe in any suitable manner and the table taking the place of the posts 1. and 10.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as follows, modifications within the scope of the claims being expressly reserved.

1. In a shoemakers jack, a hollow support having two pairs of oppositely placed inclines and a depression between each pair of inclines, a tilting post carried thereby and having its lower end adapted to fit the top of said support, depending slotted ears on said tilting post, pins passing through the support and the slots in said cars, a post having a turn table carried by the tilting post, and a removable last on the top of the last mentioned post, substantially as set forth.
